Product Description

Fosroc Conbextra TS is a high-flow, non-shrink, aggregate filled cementitious grout conforming to the requirements of BS EN 1504-3 Class R4.

Best Uses

Conbextra TS is used for free flow, non-shrink, cementitious grouting for gap thicknesses 75 to 500 mm. Recommended applications include stanchion baseplates where a large gap is present, joints between pre-cast concrete panels and filling box sections.

  • Non-shrink
  • High strength
  • Chloride free
  • Can be pumped or poured
  • Suitable for thick sections

Conbextra TS is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free-flowing grout for gap thicknesses 75 - 500mm. In addition the low water requirement ensures high early strength and long-term durability.

Conbextra TS is a blend of Portland cements, graded fillers, selected aggregates and chemical additives. The filler grading produces a highly flowable grout which will not segregate or bleed and reduces the exothermic heat generation and risk of thermal cracking common with gap thicknesses in excess of 100 mm.

Application

Preparation is depending on situation. Please refer to product data sheet for full application guidance.
