Locally owned, Alaska-wide
Alaska Concrete Technologies Inc. dba Mobile Concrete and Grout of Alaska is a locally owned company incorporated in 2000, providing concrete and grouting services throughout Alaska. Terry Waschke, owner, has over 40 years of experience in the production, pumping, and quality control of concrete and grout. Portable batch plants, mixer trucks, volumetric mixers, and super bags, individually, or in combination, are used for concrete and grout production, anywhere in the state.

Batching
Terry has 30+ years experience batching with computer-controlled dry batch and central mix stationary plants, a computer-controlled portable dry batch plant for remote projects on the road system, a volumetric Mixer with computer for local and remote projects, and Fastway plants for remote projects with local…

High Performance Concrete
Projects such as bridge deck overlays and tunnel linings require concrete or shotcrete strengths in excess of 10, 000 psi. Very low water to cement ratios are used to achieve high strengths, in conjunction with additives like Silica Fume, along with plasticizers, retarders, and air entrainment admixes. Stringent QA/QC…

Cellular Concrete and Grout
Cellular Concrete is made with pre-formed foam added to either a sand, cement, and water, or neat cement and water, to achieve densities between 30 pcf and 110 pcf, and strengths between 75 and 1,200 psi. It can be pervious or closed cell.

Remote Concrete
Remote is considered anywhere far enough away from our base that equipment, materials, and personnel individually or together have to be shipped in by truck, barge, ferry, or plane. As there are limited roads in the state, most shipping is by barge and plane.

Concrete Pumping
Terry has 40 years of experience pumping concrete with boom pumps including Thomsen, Challenge, and Putzmeister, as well as many line pumps, including Challenge squeeze pumps and Mayco, Schwing, and Putzmeister swing-tube piston pumps.

Concrete Consulting
Due to many years of remote concrete production, Terry knows what the most cost effective and efficient method to get materials and equipment to most any remote location. Most of my projects are very difficult because of the location and/or characteristics of the job. We work with local providers around the state for…
Grouting Services
Stabilising soils, raising slabs, filling voids and grouting pipelines.

Compaction Grouting and Foundation Repair
Compaction Grouting is the stabilization of poor soils under buildings, structures, roadbeds, railroads, or runways, by driving injection pipes down to stable ground and then injecting low-mobility grout to densify soft soils and form grout columns. Injection is continued in a pattern to cover all of the target area…

Void Filling and Abandonments
Filling voids or pipes can be as easy as plugging both ends of a pipe and filling with grout, or as complicated as figuring out the mix and method to inject grout 40' underground through a spring-loaded, expandable steel form with an inflatable plug to fill a void.

Slab Jacking, Slab raising, Floor raising, or Mud jacking
Slab jacking is the raising of sunken or settled concrete floors by drilling holes and Injecting grout underneath.

Sliplines and Annular Space Grouting
Low-density cellular concrete, or grout is used to fill the annular space between an older damaged host pipe and a new plastic liner pipe, usually HDPE. The pipes can be for sewer lines, or culverts under roads or railroads. The grout density is usually kept between 40-55 pcf which is lighter than water so that the…

Grout Pumping
We use the same Putzmeister swing-tube line pumps for grouting as well as concrete. The difference for most applications is that we slow down the pumps to a minimum output. For underground grouting the volume measurements are in cu ft per min and with the TK20 we can pump down to 1 cu ft per min at 2000 psi line…

Chemical Grout, Polyurethane
Polyurethane expanding foam can be used to fill voids and lift slab sections in some cases. There are many suppliers and many different types to do similar things. We use a two part polyurethane foam resin, heated, and injected under high pressure to fill voids and raise slabs. This works well for some applications but…

Grouting Consulting
Means and methods for a variety of underground grouting applications including ground stabilization, building lifting, void filling, bulkheading pipes for abandonment or sliplining, as well as vent and fill port locations on pipes.
