Basement waterproofing in Merrick isn’t a game of chance – it’s about applying proven techniques where needed most. Our team takes a precise approach, blending both interior and exterior solutions to eliminate moisture at the source. From heavy rain to rising groundwater, our systems are designed to keep basements dry, clean, and always protected through any season.
French drains are made to collect and redirect groundwater before it reaches your basement. They provide a first line of defense and keep your space dry beneath the surface when strategically installed around your foundation.
Sump pump systems kick in right when water begins to pile up, then removes it before any damage occurs. Installing a sump pump system is a simple, yet smart way to stop flooding during storms or rapid snowmelt.
Cracks in basement walls or floors can let water in and invite mold over time. Our foundation crack repairs will shield your basement from any issue and restore your foundation’s strength.
Grated channel drainings manage surface water before it reaches your basement walls. Driveways, patios, and entryways are common places to install them. Thay are designed to redirect excess water away from your home.
This waterproof barrier, that acts as a protective layer, is applied directly to the exterior of your foundation, making sure water is unable to get into your basement. It’s a long-term solution, especially useful in parts of Nassau County that has plenty of rain.
Water can pool near the foundation if there is poor drainage around your home. We grade your foundation to improve water flow, which keeps moisture away from your basement and reduces the risk of erosion.
Without proper drainage, water can pile up in window wells and seep through basement windows. We install window well drainage systems that channel water away, helping to keep your home dry during heavy downpours.
