Busiest Cargo Gateway Airport in the World uses Flexible Cement II – HKG Hong Kong China

Leave a comment

The Hong Kong International airport HKG is home to the world’s busiest cargo gateway airport. In 2015, HKG moved over 4.38 million metric tonnes of air cargo.  It is also one of the world’s business passenger airports accommodating over 68 million passengers that same year.

Operations at the world’s busiest cargo airport run 24/7/365 without stopping. Maintenance crews need a crack and joint repair material that can be applied in a wide range of conditions and be ready for service in minutes. Roadware Flexible Cement II  is a tough polyurethane crack repair material that can be applied at any ambient temperature. It bonds very well to distressed concrete and forms a tough semi-elastic polymer that will withstand heavy airline traffic in about 15 minutes. Crews at HKG airport have relied on Roadware Flexible Cement II to make repairs whenever and wherever needed for over 5 years.

The Control Joint Problem

Video 7 Comments

There is a big problem with control joints or contraction joints. They are the saw cut joints we cut into concrete slabs to control cracking as the concrete cures. The problem is the floor owner typically wants the floor poured, joints cut, joints filled, and building occupied in 60 days or less. Concrete cures hard in typically 28 days, but it continues to shrink and crack for a about a year.  The contraction joint that was 1/4″ when it was cut, can almost double in width in that first year leaving the 1/4″ of joint filler a bit short, cracked and generally a mess. The sidewalls of the joint are left unprotected and the joint spalling begins. You can replace all that gummy polyurea or brittle epoxy with Roadware 10 Minute Concrete Mender™ and leave your control joint problem behind.

Broken Step Repair with Concrete Mender™

Vertical concrete repair with Roadware 10 Minute Concrete Mender™ is simple if you use a few basic techniques. The following is a repair to a spalled out concrete step. As with any concrete repair, the first step is to remove any loose concrete with a chisel and clean the repair area with a wire brush and a shop vacuum. Remove all dust, dirt and loose materials. Any moisture on the concrete surfaces should be allowed to dry. On occasion, I will use a heat gun to dry the concrete.

Warehouse Floor Repairs in the Dominican Republic.

Franklin Gutierrez in the Dominican Republic is using Roadware 10 Minute Concrete Mender™  to repair multiple spalls in a warehouse floor that were causing damaged forklifts and damaged backs.

“We did 87 repairs for this client, it is a tin can production plant, they work 24/7 so there was no time to close areas for repairs , also lots of equipment very sensible to dust in the air. The major problem was that those small holes were damaging the wheels of the forklifts, damaging the back of the operators and creating possible dangerous situations for the forklift operators, because they manage very heavy loads and even a small hole could make it unstable.
We did all in two days and the client is very very happy, the problems were solved and there was no interruption for them.
This is a big plant that produces for the local market and export, its called Troquedom.” 

Loose materials are removed from the spall.

 

Bulk Roadware 10 Minute Concrete Mender™ mixed with sand is troweled into the spall. See instructions here.

 

 

Heavy forklift traffic can be restored in about 10 – 20 minutes depending on the temperature.
Roadware 10 Minute Concrete Mender™ with Microdoweling™ performance creates structural concrete repairs that will hold up under the toughest warehouse floor applications. Even if the warehouse is for frozen food and -20F or colder.
