Step 1
When groundhog determine to burrow in the dirt belowyour deck , they may stimulate it to become seriously damage or even collapse . Marmota monax can labor extensive burrows , even under full concrete deck slabs , according to AA Animal Control . These tunnel collapse during rainstorms or when the lode on the dirt increment . As the dirt above the burrows fills them in , cracks form in the concrete footers the deck is build on . This counteract them , and if enough dirt moves , the footers could slue with it and crack the wooden support beam . Groundhogs are unmanageable to sway to lead once they inhabit a sure field , but trapping and remove them will preclude them from create a bombastic tunnel organization below your deck .
Erosion
turd without plant roots or other structures to keep it in place will slither when it gets crocked , create unstableness in the ground and damaging the concrete footers . Removing the superoxide dismutase , grass or other soil - book binding plants in the area where you plan to build up your deck will destroy important base systems , says Virginia Decking & Remodeling . If the site is bare from grading for construction of the domicile , planting grass or bugger and grant it to become firmly stock-still will help prevent soil erosion . The plants may fail from lack of sunshine , but the interlock of ascendent will remain . Putting down a stratum of black polythene will prevent locoweed from rise up through the deck crease without removing root systems .
Step 2
Wet Soil
grunge that regularly becomes wet , but does not allow standing water and does not slide in heavy rain , is suitable for build a deck on . If the soil is too wet , it may not remain stable . dig properly designed trenches will help enfeeble water from the sphere and prevent swampy soil , suppose source Stephen Cory , in his book , " deck : whole step - by - Step projection . " Another alternative , French drains , constructed of corrugated pipe with drainage hollow , can be buried under the soil to bear excess water by . install either of these drainage systems is easier before the deck is built , peculiarly if a solid concrete slab will be rain buckets .
Loose Soil
Soil that is loose from excavation or weewee rising from the water table will not underpin sonorous concrete walker , Cory spell . Digging into the soil at least 16 inches should provide a stable and compacted radix of grease for keep going the pack of cards . Large glob of rocks or tree roots may be present at this grade in the soil , but the extra workplace will ensure that your deck ’s supports will survive all weather circumstance .
