How to Secure the Foundation of a Dry Rainbow Slide

Site-Ready Concrete Base

Best for natural slopes. After precision leveling, we pour a solid concrete slab. This locks the slide in place—no vibrations, no creeping shifts—so riders get that smooth, “floating” glide from top to bottom without a single wobble underfoot.

Composite & Pile Foundations for Soft Ground

For flat lots or loose soil, we don’t cut corners. We swap out weak earth for compacted lime-soil or graded gravel beds, or drive reinforced concrete piles/CFG piles deep enough to hit load-bearing strata. The result? A rock-stable base that shrugs off settling, even after heavy rain.

Steel Frame & Anchor Bolt Fixings

The slide panels sit on a rigid steel frame. At each column base, we use high-tensile expansion bolts—torqued to spec—to lock into the concrete. Every anchor plate is fabricated exactly to our engineering drawings, so you never have to worry about pull-out risks, even with back-to-back rider loads all season long.

Specialized Soil Stabilization

For tricky ground—sandy, loose, or prone to settling—we bring out the pros. Options include concrete densifiers, mechanical compaction, chemical stabilization (cement/lime blends), grouting, or soil-nail walls. These treatments knit the soil into a solid mass, giving you a foundation that stays put year after year.
