Symptoms

  • Board or slide shifts or flexes more than usual at the base
  • Visible gap or movement where it meets the deck
  • Bolts appear loose, rusted, or missing

Likely causes

  • CommonLoosened anchor bolts at the base mountingConstant flexing and weight cycling loosens bolts over a season of use.
  • CommonCorroded or degraded anchor hardwarePool chemicals and moisture corrode metal anchors and bolts over years.
  • PossibleCracked or deteriorated deck around the anchorThe concrete or decking the anchors are set into can crack, reducing their holding strength.

What to do

  1. Stop all use of the diving board or slide immediately if it feels loose or unstable.
  2. Inspect and tighten all visible anchor bolts to the manufacturer's specified torque if known.
  3. Check bolts and anchor sleeves for rust or corrosion and replace with new stainless hardware if degraded.
  4. Examine the surrounding deck material for cracks that could compromise anchor strength.
  5. If the deck is cracked, this needs professional repair before the board or slide is reinstalled and used.
  6. After tightening, test stability firmly (without a person on it) before returning it to normal use.

Tools and parts

  • Wrench or socket set
  • Wire brush (for corroded hardware)
