The technique used to keep water from infiltrating a house or other building is waterproofing. If the structure is at ground level or below, then waterproofing is necessary so that ground water will not build up in the soil which will result in raising the water table. The basement systems Nova Scotia can help eliminate some of these problems.

This causes pressure underneath the floor and walls of a basement. Small cracks will expand with the openings caused by contraction and expansion of the hydrostatic pressure. This will cause cracks in the floor joints resulting in mold and decay to form. The most common area that water enters a poured foundation is through cracks in the foundation. These can easily be sealed with epoxies that can be injected into the cracks and openings. This type of repair usually has a warranty from ten years to a lifetime by the contractor. Waterproofing Dartmouth can help with this problem.

With masonry foundations, an interior sealer will not keep the water from invading the area when pressure occurs. Spalling will occur when humidity breaks down the surfaces of the foundation causing shedding of concrete. Interior sealers can prevent the humidity from inside the area which will prevent water from being absorbed and spalling occurring.

Concrete block foundations can have an interior drain tile apparatus that will capture the water as it enters the block and drain it out with a sump pump. Weep holes will be drilled into the lowest layer of the block so that the drainage can occur. This system is a guaranteed way to provide a dry basement for years.

The water enters the basement through a crack in the foundation. A French drain or trench drain gathers the water before it enters. The drain gets the water to the sump pump and the pump directs it out of the house.

When looking to waterproof on the exterior then one is trying to prevent the molding and decaying of building supplies by preventing the water from entering the foundation walls. The IBC or International Building Code only recognizes this type waterproofing as an appropriate way to prevent structural damage by water. Before the 1980\’s the majority of the exterior waterproofing was done with an asphalt based covering which become a health hazard later.

New techniques are constantly being developing to prevent water seepage on foundations. A polymer-based waterproofing material is now in the process of production in order to last longer and be applied easier. This material will not be affected by the pH of the soil and it can be sprayed directly on the wall. The most advantageous issue is that it is fast curing and it is flexible so the movement of the substrate will not keep the product from working on the foundation.

Many waterproofing systems are available according to cost, effectiveness, and installation methods. Foundations are made of many different materials such as brick, concrete, block, and wood. Finding the right waterproofing system is important for the particular foundation.
