Approved by the UK Drinking Water Inspectorate (DWI) (per manufacturer), it withstands high positive and negative water pressure and maintains excellent crack-bridging performance even after prolonged immersion.\u003c\/p\u003e\u003c\/div\u003e\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eNitocote CM210 is a two-component polymer-modified elastomeric cementitious coating supplied in pre-packaged form. It is mixed on-site with a slow-speed drill and paddle, then applied to form an elastomeric impermeable membrane. Available in grey and white, the product is designed for waterproofing water-retaining and water-excluding structures such as potable water tanks, reservoirs, canals, and culverts. It can be applied to concrete, brick, and blockwork substrates and maintains excellent crack accommodation even after long-term water immersion — a condition many cementitious coatings cannot satisfy.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003ePotable water approved\u003c\/strong\u003e — Approved by the UK Drinking Water Inspectorate (DWI) (per manufacturer)\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eHigh water pressure resistance\u003c\/strong\u003e — Withstands high positive and negative hydrostatic pressures\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCrack bridging after immersion\u003c\/strong\u003e — Maintains excellent crack accommodation after prolonged water immersion\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eStrong adhesion\u003c\/strong\u003e — Excellent bond to concrete and masonry substrates\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDamp surface application\u003c\/strong\u003e — Can be applied directly to green or damp concrete\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eChemical barrier\u003c\/strong\u003e — Effective barrier to sulphates and chlorides\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eVersatile application\u003c\/strong\u003e — Suitable for brush, roller, trowel, or spray application\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eAmple working time\u003c\/strong\u003e — Sufficient working life after mixing\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\u003cli\u003ePotable water tanks (rooftop and underground)\u003c\/li\u003e\u003cli\u003eReservoirs and water storage facilities\u003c\/li\u003e\u003cli\u003eCanals and culverts\u003c\/li\u003e\u003cli\u003eBasements and underground structures (resists negative water pressure)\u003c\/li\u003e\u003cli\u003eConcrete, brick, and blockwork structures\u003c\/li\u003e\u003cli\u003eWater-retaining structures requiring long-term immersion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003ePackaging\u003c\/h2\u003e\u003cp\u003e23KG per set (18kg powder component + 5kg liquid polymer).

CM210 resists both positive and negative water pressure with higher elasticity, making it ideal for underground tanks subject to external water pressure. Brushbond offers better breathability, making it more suitable for rooftop water tanks where moisture vapour permeability is needed.\u003c\/p\u003e\u003ch3\u003eCan CM210 be used for basement waterproofing?\u003c\/h3\u003e\u003cp\u003eYes, it is well suited for this application. CM210 resists negative water pressure (groundwater pushing from outside through the structure), making it an ideal choice for basement and underground waterproofing. It can be applied directly to damp concrete surfaces without waiting for the substrate to dry completely.\u003c\/p\u003e","brand":"Fosroc 富斯樂","offers":[{"title":"Default Title","offer_id":42397801971862,"sku":"","price":1.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/9027\/1382\/files\/Nitocote_CM210.png?v=1776659385","url":"https:\/\/wahhingwp.com\/en\/products\/fosroc-nitocote-cm210","provider":"華興建築防水材料有限公司","version":"1.0","type":"link"}
