High performance polymeric sand, HP Nextgel is ideal for pavers, slabs and hardscape installation. Techniseal® HP NextGelTM Jointing sand is a state-of-the-art mix of specially sorted sand and binders that flows smoothly down joints for a fast and effective installation of pavers or slabs with false, narrow or wide joints. It is also recommended for surfaces exposed to heavy traffic, and for high-humidity areas. Easy to use, HP Jointing sand starts to set only a few minutes after being activated with water, and quickly becomes resistant to water erosion (rain, splashes, sprinklers, etc.). NextGelTM Jointing sand offers great resistance to weed growth, insect invasion, and erosion. Techniseal® HP NextGelTM Jointing sand has been manufactured with a revolutionary technology called NextGelTM. NextGelTM radically transforms and improves the properties and behavior of jointing sand, resulting in the first ever true “no dust”, “no haze” and “no waste” jointing sand for a fast, clean, durable and profitable installation.
