Make Us Your Preferred Grading and Drainage Contractor
Moisture is one of the biggest enemies of property foundation, and as luck would have it, the material that surrounds the base of your house can absorb any kind of moisture. The single most important thing a person can do to improve the health of their foundation, thereby avoiding a wet basement, is to keep water away from the foundation in the first place. Whether you need an interior or exterior foundation drain, a surface French drain, cut-off drain, or just need your lot regraded so that precipitation can naturally flow away from your home, Van Matre Construction can help.
If you have issues with a wet basement or crawlspace, and your exterior grading is in good shape, a foundation drain may be the solution you need. A foundation drain may be placed inside or outside your foundation, allowing ground water to collect in the horizontal drain, flow to a sump pit, and be pumped safely away from the home.
The worst part about an exterior foundation drain is the disruption to landscaping. The installation requires excavation of the exterior of the foundation to the base of the footings (or wall if it is poured on drilled caissons). Once the wall is excavated, we clean the wall, inspecting for cracks that may need attention. Van Matre Construction uses only the highest quality materials: While other companies spray the wall with asphalt, we cover the wall with Cetco brand AquaDrain . The solid plastic backing ensures no water will make it to your foundation, the dimples give a clear path for water to fall to the horizontal drain at the base, and the geo-textile fabric adhered to the face ensure that the product will not clog with mud. This quickly takes water to the base of the drain system. At the base, Van Matre installs a perforated pipe, wrapped in geo-textile fabric, surrounded by a foot of gravel, and again wrapped in geo-textile fabric. The base drain slopes gently downhill to a sump pit where a high-quality cast-iron pump removes the water-pumping it away from your home.
An interior foundation drain is placed just inside the foundation wall and footing, beneath the basement floor slab. An interior drain spares your landscaping, but does not allow for waterproofing of the exterior of the foundation wall. The foot wide swath of floor slab is cut and removed around the perimeter of the basement, and the underlying soil removed to the base of the footing, usually about 8”-10” from the base of the floor slab. Similar to the drain at the base of the exterior drain, a perforated pipe wrapped in geo-textile fabric is surrounded by gravel and wrapped in another layer of geo-textile fabric. The pipe slopes gently downhill to a sump pit where a high-quality cast-iron pump removes the water, pumping it away from your home. The floor slab is patched and the job is complete.
