Problem Solving in the Waterproofing Industry

With the truth in the statistics it is clearer than ever that home renovators and property owners face unfortunate odds when it comes to waterproofing. The answer is in education.

Waterproofing has been around a long time, liquified heated tar was used in ancient times to waterproof objects and materials and even today tar and oil based waterproofing is still in use. But the construction has changed, we now rely on thin walled products, fibre cement, plaster and timber frame construction. The mass of a building will no longer provide security against the ingress of water. This is probably the reason why more than ever before we see the rise in water problems.

Architecture has opened up many possibilities in design for balcony construction over living spaces, light wells, roof top decks. But these come with strict requirements, sadly the building industry can be rife with poor adherence to the standards required in these critical areas. Areas where not only UV light and heat play a massive role but wind force and building subsidence. People are not aware of the massive force these exert on the subfloor membranes, most often the only layer separating the occupier from the outside elements, namely water.

The cost of rectification is astronomical in comparison to what a properly scoped waterproofing system would be. It’s true to say a stitch in time saves nine. In most cases sheet membrane systems are the most effective in creating extremely long lasting external membranes, spray on polyurethane and liquid rubber come close second.

Stricter enforcement of the standard of waterproofing requirements is absolutely necessary but until this becomes legislated and legally binding in the construction industry home owners and builders must educate themselves and ensure the strict requirements for watertight construction is followed and if possible exceeded.

Simple it seems but to change people and industries with current set practices is very difficult. People are afraid to be wrong, afraid to admit that they have not been strictly thorough in the past. To change is in a way an admission of guilt in this. And it is this which we are up against on the peer to peer level.

Be assertive in your demands for a performance waterproofing system. Ensure you have a qualified trades and an experienced set up for the waterproofing both in your bathroom and out. Know the requirements for wet areas and choose carefully when selecting a contractor to carry out the works. Professional trade waterproofers will have high attention to detail as the work requires. Hire dedicated specialists over tiler/ waterproofers and builder handyman waterproofers. Specialists base their income on the security of the work they provide whereas all in one workers have multiple concerns and more often than not these are the jobs that fail.

We have to surrender total control to others in the day to day, but that doesn’t have to mean we are forced to accept the low standards that proliferate some levels of the construction industry. Choose quotes based on the merits of their level of expertise, past jobs and if they hire specialists, choosing a quote based on costs alone is wrong. You will always invest more in quality, but it will stand the test of time and save money in the long term.

How Has Computer Aided Drafting (CAD) Revolutionized Engineering Industry?

CAD, Computer Aided Design has brought about a technical revolution in the Engineering Industry. CAD Services can be classified into broad categories like Architectural Services, Structural Services, MEP and Mechanical Services. CAD for Engineers and Architects today is like Oxygen for the living. CAD Services is a boon for all companies’ worldwide who would like to execute CAD projects with minimum cost and quick deliverable capacity. With the consistently growing demands in construction industry and CAD services have achieved eminence across the globe. This technology has contributed immensely in development of Construction Industry, Building and Infrastructure development, Green Building concept along with other Engineering Domains like Machine Designing, Aeronautical sheets, Transformer designing, GIS, Pressure vessel designing etc..

Engineering industry today uses CAD Services to ensure Less cost, best quality, quick turnaround time along with excellent project efficiency. CAD is no longer limited to AutoCAD. There has been a great evolution in the CAD Software too. CAD professionals globally use software which is helpful in are using latest software like AutoCAD, Revit, 3D Studio Max, Pro-E, Solid Works, Inventor, MicroStation etc to execute Designing, Drafting and Modeling projects. With the help of such software, the entire project execution cycle has come to a new arena due to CAD Services. It is now possible to visualize an entire building and it’s detail even before it is completed. This is possible with the help of “Virtual Construction Modeling” also referred to as Building Information Modeling in Engineering Industry. 3D Rendering makes it possible to give any building or product a photorealistic feel before the actual construction or manufacturing of a product. This development has also caused increase in companies providing Engineering and CAD Services. With transformation of blue prints created manually to digitization of CAD Drawings, many opportunities have opened up for Architects, Engineers and Drafters.

CAD services assure absolute digitization of manual drawings to computerized drawings via scanned pdfs, hand-drawn sketches or old manual drawings. Companies are using different approaches and techniques to take utmost advantage in terms of project execution. As mentioned earlier, CAD Services are no longer limited to one particular domain or segment. Arrays of services are covered under one umbrella. Besides project execution, computerized CAD Drawings or Images are easier to maintain, save or send across to clients. There is no risk of images or drawings being damaged in course of time. Errors can be rectified easily without taking much of time and can aid to quick turnaround. In software such as Revit, a change made in one part of the model reflects in the entire model by reducing manual intervention. This also facilitates definition and extraction of individual sheets or different part of drawings and every minute detail.

These are one of the main reasons that across the globe, major construction houses or Infrastructure companies are eminently outsourcing CAD Services. This process over a period helps companies gain advantage over their competitors who do not outsource their requirements. CAD Technology has evolved into a different era in a short span of time and is constantly evolving into giving better shape to the Engineering industry. CAD Services now helps CAD companies and professionals manage their Designing Drafting or Modeling projects more efficiently. Companies offering CAD Services and companies who are constantly upgrading their technical skills will always be in an advantageous position compared to companies who still rely on traditional methods of executing projects.

Responsibilities of Nigerian Professionals in the Building Construction Industry

(1)The soil scientist:

The soil scientist work is to determine how suitable is the land for the purpose of which is going to be used for.They check the strength,ph content and gives report on the effects of building on such lands.They are important indeed to avoid settlement of land due to weight of building in the future. They use different ways to investigate soil conditions.For simple residential buildings on reasonable sites digging several holes about three spits deep, drilling holes up to 2 or 21/2m deep with a hand auger or driving a pointed steel bar about 1 1/2m into the ground are generally sufficient. With larger buildings or more difficult sites,the following methods are applicable.

(i)Excavating trial holes about 1 1/2m deep deep outside the perimeter of the building.

(ii)Drilling boreholes by percussion or rotary methods.The percussion method uses a steel bit with a chisel point screwed to a steel rod.The rotary method employs a hollow rod with a rotating bit and a core of strata is forced back up the hollow rod.

(iii)Load testing often using a reinforced concrete slab about 1.20 to 1.50m2 and 300mm thick,to which loads are added at about 2 hour intervals and the amount of settlement is determined with a level .The safe bearing capacity of the soil is found by dividing half the load applied prior to appreciable settlement into the area of slab.


Lawyers are needed right from when you want to purchase your land,they help in all legal dealings. From contracts to agreements between you and the “omo onile” landowners; you need them .It is the job of a lawyer to find out the true owner of the land because the person selling to you may actually not be the right person to do so, they will do a thorough scrutiny on the agreement papers and give their legal advice on your investment.The money you pay for this service may be worthwhile considering the possibility of losing your money if you refuse to contact them.

(3)Land Surveyors:

These people map out the the area or plot of your land.They see to it that your land is properly demarcated from your neighbour with their instruments and skill they will give you the accurate length of your plot .There drawing is what you take to the architect for design of your building. You also needs survey plan for validation of your land when you want to register it.


They liase with you i.e the clients on one on one to achieve the type of building you want .Architects give professional supports to the clients not only on the design of the building ,the execution ,but general support even the viability of the building .The work of an architect is extensive because they are generally closer to you clients than every other building professionals. He is in the best position to know what meets your dreams and how to help achieve it. He conceives or dream and put pen to paper and sketch out what you have in mind,gives you to criticise to suit what you want properly, and make the necessary adjustments .He is the bridge between you and the other professionals and artesans on site ,by his position he is the head of the building team.

(5)Quantity Surveyor:

This professional estimates and see to it that you won’t embark on a project that is beyond your financial means .They cost and determine the amount of money you will require to build your house so that you don’t end up abandoning your project midway. This people are very important unfortunately Nigerian of today do not see the need for them and that is why we have abandoned projects dotting our landscape. It is nice to have a beautiful and befitting house .It also helps to promote the architects that designed it for you when your house is very beautiful, though for small projects your architect can give you an idea of what your building will cost ,but you may not really get the perfect and non-sentimental estimate as to what a quantity surveyor will give you. The quantity surveyor has nothing to lose if the house is very ugly his job is to make sure you have a financial understanding of what you are about to embark on. On big projects ,they maintain and award money to artesans and labour based on the input each worker is putting.

(6)Civil or Structural Engineers:

The civil or structural engineer in building industry is to see to it that, the stability or structural disposition of your building is not compromised. I mean they give calculations and recommends based on the Architect’s drawing, what kind of reinforcement or iron or any other structural elements that can make your house stable and will not collapse. And they come out with the drawings on this to help the builder on site to carry out is work effectively.

(7)Mechanical Engineer

These people see to the mechanical aspects of the building especially large projects they give out detailed drawings and specified on plumbing work in the building, the plumbers work with them and help carry out instructions for the good of the project.

(8)Electrical Engineer

As the word implies they see to it that there house is properly lightened. Dangerous electrical connections has led to the death of several people. I will advise you have the electrical engineer in your plans when embarking on a building project. They give instructions to the electrician on large project sites.

(9)The Builders

These are one of the most important professionals in the building industry, unfortunately, the Nigeria of today is a case of dog eats dog. A situation where you claim you can do the work of somebody else and no law to discourage you against such impersonation that is what we are seeing in the building industry at presence. “Collapse of buildings” The builder is trained to carry out or execute on site or transform or bring into reality on site the drawings and intentions of every other building professionals, may it be the Architects, the Civil Engineer, the Mechanical Engineer and the Electrical Engineer. His duty is to see to every artesans or workers on site carries out is job effectively. Unfortunately every jobless person with some money in Nigeria are now claiming to be building contractors and people out of ignorance do not even know the difference.

Even other professionals too are jostling for each others job. A situation where a town planner or a surveyor lays claim to the fact that he can design a house plan for you or when a quantity surveyor is doing the work of a builder will not give you the best you deserve. A building contractor yes, is important in a construction industry but their work is not to bypass any professional rather they are to work with the professionals or consult with them to carry out the project effectively except if the contractor is a professional himself. They are probably the one to finance the building project at times, but to get a very good job you must insist on knowing the professional they will be working with.
