Three ways to make leak-free flooring for containment pit
After establishing a curbing enclosure as spill containment pit, the key challenge is now shifted to making a leak-free flooring so that the containment pit can function as designed. The basic requirements for a containment pit flooring are:
Based on these requirements, Land and Water Group offers 3 best ways to make leak-free containment pit floorings.
LW-FRPC is a pre-mixed fiber reinforced polymer concrete material and supplied in drums. Each drum contains a dry mixture of cement, sand, pea gravel, macro fibers, and special admixtures and additives in predetermined proportions. The only ingredient missing from the drum is water, which will be added on site prior to site mixing. Upon adding water, the mixture should be mixed thoroughly, and poured immediately to form a spill containment flooring.
LW-Tile is a modular precast concrete tile block. It is lightweight, easy to cut and fit, and is load bearing. Around the edge of the modular block is a strip of extruded expansible rubber water stop which will swell when meeting with water, forming a complete leak-free joint. The modular blocks will be placed tightly against each other to form a waterproof floor slab, and the joints will be further reinforced by polyurethane caulking.
The Concrete on Mesh method is a process that involves placing the wire-meshes at midway of the intended floor depth, pouring concrete with pre-planned grooves at all joints, and provide caulking on the grooves.
