NRI

A Nebraska family owned corporation.

"Small enough to know you and large enough to serve you!"

Installation of mats explained:

Steps:

1) Level the area, take out high spot(s), and smooth out any humps.

2) Spread out crumb rubber

3) Use 4' to 6' long 2x4 to (secrete) level out the rubber

4) Start your first row of mats by either going North and South or East and West.
(NOTE: When laying the mats, you may want to put a mark at 2 foot on both sides of the mat to make it easier to line up or set in place.)

When installing at ground level, excavate area to 1 1/2" depth, level the base with dirt, sand, gravel or crumb rubber*. Apply silicone adhesive (we recommend 100% RTV Silicone Rubber Adhesive) to overlap seams. Any clear or colored silicone may be used to finish top seams if desired.

5) Start your row going the opposite direction that you started in Step 4 and make sure that you are keeping your rows square.

6) Cut your corner to fit. It could be the top or bottom mat. Tip: Score notch to be made with knife and use pruning shears (10” handles) to cut notches *

7) Use a saws-all or variable speed saw (course-wood blade) to cut around any play structure legs if piece cannot be moved.

8) Clean bottom lip (overlapping edges) of any dirt or crumb rubber

9) Pull the top mat half way and glue lips. Do the other sides in the same manner, continue until all mats are cleaned and glued.

10) Blow out any remaining surface cracks, fill with caulk and level caulking flush with surface.

*Four corners of mats: Usually one or two of the mats lips (overlapping edges) will overlap a mat that has already been installed. Before setting a mat with a sledgehammer, the overlapping edge will need to be notched. Sometimes it will be one mat and other times it will be two or four mats. Both top and bottom lip corners may need notched to get a proper fit. Your seams will be staggered because your edges are overlapping. This also adds strength to the installation.

Tools Recommended

1. 1 -2x4 & sledge hammer
(used along the side of sheets to assure tight fit)

2. Small caulk gun

3. Variable speed saw (electric)
(We use a DeWalt Saws All)

4. Carpet Knife

5. Lg. Carpenters Square

6. Chalk Line & White marking pencil

(all tools not necessary for every installation)

When installing at ground level, excavate area to 1 1/2" depth, level the base with dirt, sand, gravel or crumb rubber*. Apply silicone adhesive (we recommend E6000 Sealant) to overlap seams. Any clear or colored silicone may be used to finish top seams if desired.

 

* To meet fall height criteria, additional excavation depth will be needed. When using crumb rubber as your base to meet a 8-12 foot fall height, 2" - 3" of crumb would be needed and excavation to a depth of 2 1/2" - 3 1/2" is required. Crumb rubber will settle approximately 1".
