Tilt-up and precast panel joint caulking

The distribution buildings along I-70, E-470 and the airport corridor are concrete panels connected by sealant. When those vertical joints open, the warehouse leaks. We reseal them.

From Buckley Joint Sealants, a commercial caulking contractor in Aurora, quoted against published pricing.

Why panel joints fail first in this climate

A tilt-up panel is a slab of concrete 25 to 40 feet tall that grows in the afternoon sun and shrinks overnight. On a Denver metro summer day a dark panel face can reach well over 120 degrees, then drop 50 degrees by morning, and in winter a chinook wind can swing air temperature 40 degrees in a day. Every one of those cycles opens and closes the joint, and the sealant absorbs all of it. Add high altitude ultraviolet, which the EPA notes rises several percent for every thousand feet of elevation, and a single stage polyurethane that would last 15 years at sea level is often hard and split by year ten in Aurora.

Vertical panel joints go first, usually at the panel shoulder where the bead loses adhesion. Then the horizontal joint at the slab and the reveal joints at the roof line. Once water is behind the panel it runs down the inside face, shows up as a stain on the slab, and in winter freezes in the joint and spalls the panel edge.

What we reseal on a tilt-up or precast building

Vertical panel to panel joints, top to bottom. Panel to slab joints at grade, which take the most water. Roof line and parapet cap joints. Reveal and rustication joints cast into architectural precast. Dock door and man door perimeters where the frame meets the panel. Penetrations for conduit, gas lines and downspouts. Each gets a movement rated sealant sized to the joint, and on wide joints past two inches we specify a two part urethane or a precured silicone strip rather than forcing a gun grade bead to do a job it was never designed for.

Working around a live warehouse

Most of our panel work happens on occupied buildings with trucks in the dock. We sequence elevations so no dock door is blocked longer than a shift, keep the lift out of fire lanes, and schedule the dock face for weekends when the tenant needs it. The survey names the sequence so the property manager can tell the tenant exactly what to expect.

The panel reseal sequence

  1. 1

    Survey every elevation with a lift or drone photos, count panel joints and measure joint width at several heights.

  2. 2

    Adhesion check on a sample of joints to confirm the substrate will hold new sealant without a special primer.

  3. 3

    Quote per linear foot by elevation, ground reach and lift reach priced separately, dock face sequence agreed with the tenant.

  4. 4

    Cut out old sealant, grind panel faces clean, install new backer rod sized to the joint.

  5. 5

    Prime where required, install sealant, tool for full contact, pull test after cure.

  6. 6

    Photo closeout by elevation and a written warranty.

Questions from warehouse and flex building owners

Our tilt-up is 12 years old and the joints look fine from the ground. Should we wait?

Have them surveyed. At year 12 in this climate the bead has usually lost adhesion at the panel shoulder even where it looks intact, and the survey costs nothing. Resealing before the first leak is cheaper than resealing after a tenant claim.

How many linear feet of joints does a typical warehouse have?

A 100,000 square foot tilt-up usually carries 3,000 to 5,000 linear feet of vertical panel joints plus the slab and roof line joints. At our published rates a full reseal on that size building commonly lands between $20,000 and $55,000 depending on how much is lift work.

Do you do new construction panel caulking for general contractors?

Yes. We bid tilt-up and precast sealant scopes for GCs on new buildings in the Aurora and airport corridor and quote them off the same per foot table, with submittals and data sheets included.

Can you match the panel color?

Sealants come in standard grays, tans and whites and most manufacturers offer custom color matching for a modest upcharge and a lead time of a few weeks. On painted panels we usually seal in a neutral and the painter overcoats with a paintable urethane.
