White Mountain granite and Littleton Formation schist along corridors like I-93, US-302, and NH-16 create foundation and void challenges. When foundations settle or sinkholes open, New Hampshire needs a contractor that diagnoses the subsurface problem first.
Access Limited provides micropile foundations in glacial till and void stabilization.
Access Limited addresses subsurface instability across New Hampshire with grouting, sinkhole repair, micropile foundations, and foundation underpinning — each engineered for the void, soil, and groundwater conditions beneath the site.
Compaction grouting injects stiff mortar to densify loose soils — restoring bearing capacity beneath settled New Hampshire infrastructure. Spider Excavators access steep and constrained sites.
Slurry grouting fills larger voids. Permeation grouting creates impermeable soil masses. Chemical grouting addresses fine-grained soils. Each is selected for New Hampshire site conditions along corridors like I-93, US-302, and NH-16.
Sinkhole repair combines void-filling grouting with micropile foundations that bridge the unstable zone. Emergency sinkhole response is available 24/7 across New Hampshire.
Micropiles deliver high-capacity support through variable soils. Foundation support and underpinning extend compromised foundations to competent bearing strata. Tiebacks provide additional capacity where needed.
