Rhode Island's compact landscape concentrates its landslide risk on coastal bluffs and the state's limited inland rock cuts along I-95, where Narragansett Basin metamorphic rock weathers into a residual soil that, combined with the state's coastal storm exposure, produces slope failures RIDOT addresses on a smaller geographic footprint than most states but with comparable engineering complexity.
This pattern is consistent with the broader Steep Slope Stability Issues challenges GSI addresses across the state.
GSI's soil nail walls for Rhode Island's coastal bluff and rock-cut slopes anchor into Narragansett Basin bedrock, accounting for this formation's specific metamorphic structure rather than generic New England assumptions. GSI's soil nailing capability supports this step.
Rhode Island's coastal storm exposure adds wave-driven saturation to standard groundwater infiltration — horizontal drains are designed to manage both sources on the state's most exposed bluff sites. This is one application of GSI's broader Soil Nail Launcher™ expertise.
Weathered Narragansett Basin residuum near the coast often cannot support conventional drilling once storm-saturated — the Soil Nail Launcher™ installs regardless of that saturated condition. GSI's horizontal drains experience informs this approach.
This approach is informed by GSI's broader landslide emergency response work across Rhode Island.
Engineered for Rhode Island's conditions. GSI accounts for Rhode Island's combined coastal storm exposure and Narragansett Basin bedrock structure — a compact but distinct engineering profile from inland New England slopes. It's backed by GSI's broader general contractors and asset owners capability.
Design/build delivery. One team designs and builds — closing the communication gaps that separate design from construction.
RIDOT specification compliance. Engineering records and field methods satisfy state DOT requirements from the initial submission.
RIDOT partners and Rhode Island infrastructure owners describe GSI's landslide repair results.
