What is Mapei FOAMJET T used for?\u003c\/h4\u003e\n\u003cp\u003eFOAMJET T is a two-component polyurethane injection resin used for waterproofing structures affected by strong water ingress. Applications include tunnels, shafts, dams, bulkheads, diaphragm walls and underground excavations. It can also be used for ground consolidation.\u003c\/p\u003e\n\n\u003ch4\u003e2. Can FOAMJET T be used where water is actively leaking?\u003c\/h4\u003e\n\u003cp\u003eYes. FOAMJET T is designed for injection waterproofing in structures subject to strong water ingress. In contact with water, it reacts to form expanding polyurethane foam that helps seal cracks and cavities.\u003c\/p\u003e\n\n\u003ch4\u003e3. What is the mixing ratio for FOAMJET T?\u003c\/h4\u003e\n\u003cp\u003eThe mixing ratio is 1:1 by volume, using a suitable two-component injection pump. The two components are mixed at the injection nozzle through a static helicoidal mixer. Follow the manufacturer's equipment and application instructions.\u003c\/p\u003e\n\n\u003ch4\u003e4. Does FOAMJET T expand when injected?\u003c\/h4\u003e\n\u003cp\u003eWhen FOAMJET T comes into contact with water, it forms polyurethane foam that expands to fill cracks and cavities. In the absence of water, it hardens without increasing in volume.\u003c\/p\u003e\n\n\u003ch4\u003e5. How much FOAMJET T is required per litre of cavity?\u003c\/h4\u003e\n\u003cp\u003eThe manufacturer's indicative consumption is approximately 1.1kg per litre of cavity in the absence of water and approximately 0.3kg per litre in the presence of water. Actual requirements depend on the cavity and site conditions.\u003c\/p\u003e\n\n\u003ch4\u003e6. What size is the FOAMJET T kit?\u003c\/h4\u003e\n\u003cp\u003eFOAMJET T is supplied as a 44kg set containing 20kg of Part A and 24kg of Part B.\u003c\/p\u003e\n\n\u003ch4\u003e7.
