ECA INTERNAL PVC WATERSTOPS for passive protection of movement joints and construction joints in reinforced concrete structures.
• Robust profile - large solid circular end bulbs promote better anchorage and embedment into concrete and simplifies site jointing
• Flexible - will accommodate large movements during construction and service life
• Pliable - remains flexible at low temperatures
• Valve action - created by concrete shrinkage around end bulbs and adjacent fin formation
• Thick web - 10 mm thickness prevents folding over and displacement during concrete pouring
• Common section for easy installation - for construction and expansion joints subject to thermal movement and deflection
