Crocodile Multi Purpose Grout is a uniform blend of finely graded silica aggregate, portland cement, expansion agent and other admixtures. Crocodile Multi Purpose Grout is a ready-to-use fluid non-shrink grout specifically for applications where grout is to be pumped or poured into restricted spaces. Typical applications include support of structural elements such as precast walls, beams, columns and panels. Other applications include filling voids around door frames, between precast wall panels, block outs and many other types of narrow or confined areas in concrete construction.
The concrete bonding surfaces must be thoroughly cleaned to remove grease, oil, dirt, laitance, curing compounds or other contaminants. All loose and unsound concrete must be removed and surface should be roughened. Moisten the concrete bonding surfaces for 4 hours prior to grouting. Remove all excess or standing water from concrete immediately prior to grout placement. Forms must be strong, securely anchored, shored and sealed to prevent grout leakage
Mixing water quantity is suggested only as a guide. Always use the minimum water quantity which provides adequate flow ability or fluidity to enable proper placement of the grout. Use only potable water for mixing. Pre-wet and drain mixer for the initial batch. Place the measured mixing water into the mixer. Start the mixer and slowly add the grout. After the grout is added continue mixing for approximately 2 minutes to ensure uniformity. When grouting areas over 3 in. (75 mm) in depth, add 25% by weight 5 kg) per 20 kg Bag of clean, uniformly graded 3/8” (9 mm) maximum size pea gravel. Mix grout to plastic or pourable consistency when using pea gravel extended mixes.
Crocodile Multi Purpose Grout can be easily pumped using a piston type grout pump. Grout should be placed under structural elements continuously and from one side only to avoid the entrapment of air pockets. Voids can be removed by rodding, strapping or chaining, however, excess working of fluid mixes should be avoided. Multi Purpose Grout remains pump able for approximately 30 minutes.
20 kg (bag) per 0.011 m3 or 91 bags per 1 m3
All grout surfaces should be kept damped for 3 days.
