Proper water drainage, both above ground and under ground, is an important element in maintaining structural integrity of the surface pavement and foundation of buildings.
Penetration of water through cracks on the asphalt, as well as ineffective underground drainage, can weaken the substructure (sub-base), causing a “quick-sand” effect, which result in more cracking and potholes. In winters, the surface water ponding or percolation of ground water can freeze, posing a safety hazard.
Clogged underground drainage can lead to foundation damage and soil destabilization which can result in wet basement or sinking of concrete driveways.
For surface water management, we design and install Gutter Downspout, Catch basin, and Lateral – French drains system.
For underground drainage, we can assist you with perimeter drainage system maintenance and installation.
CATCH BASIN WORKS:
For new or replacement catch basin installations:
We use locally made precast concrete basins, troughs, and inlet grates which conforms to MMCD, Ministry of Highways, municipal and various other regulatory bodies’ specifications.
Catch basin repair:
Some sunken or uneven catch basins can be either partially concrete rebuilt or adjusted by using permanently grouted, grading adjustment rings which provide proper grade and a barrier to infiltration.
After the repair and concrete cures on the catch basin, a 2″ basecoat asphalt is applied and compacted, then a 2″ topcoat is compacted on and all seams are sealed. This is to ensure proper water sealing.
Lateral Drain (French Drain)
When an ideal slope in a driveway which patterns the water flow away from a building or parking area cannot be attained, to prevent water pooling or entering a building, Lateral drains are installed. Referred to also as French drains, it intercepts a wide and shallow water flow to a drain system. Thus, it is often installed at the entrance point of a building, at doorways and garage doors.
What does Perimeter Drain do?
A perimeter drain prevents water from seeping into your basement by collecting water in the soil that has accumulated from rains, melting snow, or from rising groundwater, and direct it away from your house.
The Perimeter drain are made of plastic or PVC perforated pipes, and is installed underground, around the perimeter of your house. The perforations or slits in the pipe allow water to enter the pipe which is then drained away from the foundation of the home. A mesh, a permeable “sock”, is slipped over the pipe to prevent soil from getting into the pipe.
The trench is back filled with layers of gravel of graduated sizes (largest close to the pipe, followed by smaller gravel), and finally with soil. The gravel allows freer water flow towards the drainage pipe and filters out any dirt and debris that may clog the pipes.
It is significantly more economical to install or repair Perimeter drainage when you are repairing or replacing your driveway. It is because the equipment and operators needed would already be on site, and this would reduce mobilization and labour costs.
If you have water stains in your basement walls or water pooling close to the foundation of your building, you may have either a clogged or a collapsed perimeter drain. If left not repaired, it can lead to further cracks on the foundation and soil de-stabilization, ultimately, to molding in basement, flooding or concrete slab sinking.
