GROUTING & SEALING
Trenchless rehabilitation for sewers & manholes with leaky joints & small cracks
For sewers with leaky joints, leaking laterals, and small cracks, grouting remains the most effective and economical means of trenchless rehabilitation today.
Although chemical grouting is not a structural repair, it’s an effective water-stop and is particularly suitable for pre-cast manholes and sewer pipes that have leaky joints and/or pipe penetrations.
Mainline & Lateral Grouting
Since our start, Green Mountain Pipeline Services has been providing grouting services for a multitude of clients within pipe sizes ranging from 4 to 48 inches in diameter. With our specialized equipment, we can cost-effectively seal leaking mainline joints, lateral connections, and associated manholes.
Manhole Grout Injection
Sealing manholes via chemical grout injection involves drilling holes in the general area of leakage and then injecting grout to form a watertight barrier in the soil behind the manhole wall. The drill holes are then plugged with cementitious compounds.
Although chemical grouting is not a structural repair, it’s an effective method of sealing pre-cast manholes that have leaking barrel joints or pipe penetrations.
