Mx 131 Dren

Draining screed

DESCRIPTION
Premixed product, in powder form, based on cement with aggregates selected for granulometry, characterized by a high drainage capacity.


USES AND APPLICATION METHODS
MX 131 DREN is ideal for the construction of pedestrian paths, sidewalks, nature trails, public gardens, and cycle paths, even in areas subject to landscape protection. The high draining capacity allows rainwater to penetrate the ground avoiding the roots of the plants. The product can be kneaded by hand, with a continuous mixer, or with a glass mixer, being careful with the latter that mixing times do not exceed 3 minutes. Mix with water until reaching the consistency of the "wet earth" type and apply to the appropriately prepared substrate. The application can be done manually with special equipment or road pavers. During the laying operations, compact and level with special layers. Make expansion joints every 30 square meters. Protect the treated surfaces from rains, with sheets, to promote the correct maturation of the product.
