EPDM base underside plastic construction program requires a basketball court, asphalt concrete pavement or hydraulic soil basis, and requires a certain amount of strength and stability (cement concrete foundations need to cut expansion joints, may not waterproof layer.) 2, foundation non-uniform distribution of production due to cracks and frost heave caused. 3. There must be a better basis for flatness and slope requirements. 4, the surface must be flat to ensure drainage 5, the surface should be kept clean and dry basis, after the completion of the foundation, the stringent requirements of the maintenance period over 21 days. Construction process requirements. 1, the construction classification, there are two construction technology, mechanical and manual pavement paving. 2, Surface treatment: on the basis of compliance with the requirements, clean the surface first with butyl, can not exist any stolen goods, dirt, water (including the watermark), oil and so on. After cleaning, apply evenly on the basis primer (glue by 3-4: 1 ratio, stir), to enhance its bonding capacity with the ground, to avoid irreparable consequences. 3, must take note of sample test questions to do before construction. a, application of material, such as feed ratio, material curing time is normal. b, 24 hours later to see if there is not fixed and adhesion phenomena, whether the requirements of strength and the like. 4, pre-construction preparation work (manual) materials, tools and equipment (closed, Gunzi, soapy water, car, consumption, mixer, etc.) / auxiliary and catalyst preparation. 5, the construction personnel requirements (manual) standard runway construction personnel shall not be less than the minimum of six people: two preparation, haul two, paving two. 6, construction (hand) will be expected to press the proportional mix well and pour into the venue paving, heating (heating torch) or stick clappers soap water after making real, shoot flat seams, to maintain the overall level. 7, the venue thickness requirements: general construction in two to 13mm, for example: general underlying 8mm rubber particles and particles 5mmEPDM 8, Construction Notes (manual) a, best construction temperature 15-53 b, paving the tools used? (commonly known as push knife). c, mixing agitation must be sufficiently uniform. d, each batch must converge, otherwise there will be convergence of bad seams. e, when trimming must be neat. f, must be carried out in strict accordance with the proportion of ingredients. Depending on the particles on the circumstances, a good amount of water with glue, with a large difference of glue; with less large, more than a small amount. g, after the venue well, cleaning up the site residue left behind, so that the whole beautiful venue
