FUS modified sand for filling joints of paving stones, stone, paving slabs contains an innovative binder that provides high erosion resistance of joints and prevents weeds from germinating. The modified sand ensures self-healing of cracks in the joints of paving slabs or paving stones and does not shrink. Suitable for filling joints from 3 to 12 mm. It is packaged in 25 kg bags. It is available in the following colours: colourless, granite and sand. To buy a paving stone joint filler, you first need to calculate its approximate quantity, which depends on the format of the tile and the width of the joints. For tiles with dimensions of 200x100x50, 5.5 kg of joint filler per 1 m2 is required, for 300x300x50 tiles, 2.5 kg of modified sand per 1 m2 is required, with a joint width of 5 mm
Modified FUS sand has a specially selected fractional composition that ensures maximum filling of the joints of paving slabs, paving stones, terrace slabs, prevents weeds from germinating in the joints, is water-permeable, resistant to leaching and weathering. Modified FUS sand, after hardening, does not require protection from storms, under the influence of moisture, the binder is activated, which helps to close microcracks. It is recommended to use FUS modified sand for filling the joints of paving stones, paving slabs, natural stone and concrete tiles, which are laid on a drained base without binders (cement, glue). Self-healing of building materials is one of the most relevant trends, which was implemented in the FUGENSAND PLUS project by FUS. The restoration of the joints is made possible by an innovative binder that provides a very high elasticity of the cured material, which is able to change its original shape under the influence of loads arising
