Waterproofing and Leak Sealing Methods

1. Grouting method

• OverviewGrouting methods include high-pressure and low-pressure injection, suitable for fine to large cracks in concrete, with excellent treatment results.

• AppliedFor cracks in basement garages, especially those hard-to-reach tiny cracks, grouting methods can penetrate deep into the裂缝, forming a solid waterproof layer.

• Surface coatingSuitable for thin and shallow cracks where it's difficult to inject slurry, as well as cracks that are not leaking or have stabilized.

• Surface补贴Utilize geotextile membranes or other waterproof sheets for large-scale water leakage (such as honeycomb surfaces) or difficult-to-locate leakage points for seepage prevention and plugging.

• OverviewIncluding surface coating and surface patching methods, suitable for crack treatment in various situations.

• Application：

• OverviewDirectly fill cracks with patching materials (such as epoxy resin), commonly used for wider cracks.

• ApplicationFor cracks wider than 0.4mm or those containing debris that are difficult to treat with grouting, the filling method offers an effective solution.

• Waterproof paintPolyurethane coatings, with low-temperature flexibility, self-healing properties, and excellent adhesion, can be applied to floors and walls to enhance waterproofing capabilities.

• Waterproof membraneSBS modified asphalt waterproof membranes and self-adhesive waterproof membranes, suitable for large-area laying, forming a sturdy waterproof layer.

• OverviewFor larger cracks or joints, use an elastic sealant for repair, which can accommodate minor movements of the floor or wall.

• AppliedSeal joints at the garage floor and wall, and pipe penetration points with elastic sealant.

• OverviewFor larger damaged areas, use cement mortar for repairs to form a solid patch layer.

• ApplicationWhen repairing damaged floors or walls, first clean the damaged area, then apply cement mortar and smooth it out.
