Sayreville basement waterproofing from down the street

Middlesex Waterproofing is based in Sayreville, so a wet floor in Parlin or a pump alarm in Melrose is close to home for us.

That is not a sales line. The borough has a long record with water and clay, and the soil maps, the tide charts and the Sandy reports all point at the same low ground.

Clay pits and wet ground near the borough center

Clay built this place. Local deposits fed a brick industry from the early 1800s until 1970, and the NRCS soil survey for the area around the borough center still maps old clay pits across about 12% of what it sampled. The largest unit there is Galloway, clayey substratum, mixed with urban land. NRCS rates it very limited for dwellings with basements, and the reason is ground water 75 to 180 centimeters below the surface. A basement floor sits inside that band.

Clay does not let water drain off. It holds it against the wall, and when the water table climbs after a week of rain, it pushes up at the joint between wall and floor.

After the surge on Weber and MacArthur

An Environmental Law Institute case study counts more than 1,000 Sayreville homes damaged by Sandy's surge in 2012, about 300 of them substantially damaged or destroyed, and basements that collapsed in over 50. Weber Avenue, where most houses went up in the 1960s and 1970s, saw some of the worst flooding. Blue Acres later bought about 80 homes there and about 100 on MacArthur Avenue, and the lots where they stood are mowed grass now.

No basement system keeps out a storm surge. The houses that stayed are a different story: years later, many still take water through a seam, a crack or a pipe opening. Finding that path is what our leak repair work is about.

Victory Plaza and the low streets

The weather service's tide reference for Middlesex County lists Victory Plaza, where Route 9 meets Route 35, among the first places to flood in the upper part of the minor range at the Sandy Hook gauge. That is a tide reading, not a hurricane. On streets that close to tidal water, the ground stays wet near the surface, and a pit with a working pump does more than any sealer painted on a wall.

Where there is no pit, we cut one in the slab. Where there is a tired pump, we replace it, and we add a battery backup so the pit keeps emptying when a storm takes the power down. The details are on our sump pump page.

Getting to your house is a short drive

From Morgan to Melrose, nothing in the borough is far for us. We come out, look at the walls, the floor joint, the pit if there is one, and the gutters outside, then tell you what we think is going on. Sometimes it is a downspout emptying at the foundation, and we will say so.
