Quick Overview

iHow this is made

This summary is generated from the verified data on this profile: services, service area, credentials, warranty terms and the company's Google review record. It is reviewed by an editor before publishing and refreshed whenever the underlying data changes. Nothing here is asserted that is not stated elsewhere on this page.

Editorial Standards

Ram Jack of Colorado Inc traces its story to 1982, when Tim Davis Sr. and his wife Joyce started Straight Line Construction from a single truck in Pueblo. The family company took over the Ram Jack Colorado name in 2012 and now serves the Denver metro area from an office at 14020 E Davies Ave in Centennial. Its main trades are helical pier foundation repair and concrete lifting, with basement, drainage and crawl space services listed alongside them. Homeowners get a free on-site evaluation, financing is offered, and the site advertises a limited lifetime warranty. Google shows 4.8 from 160 reviews, read October 21, 2026, though most of the praise is for concrete lifting rather than water control. The office is open Monday to Friday, 8 AM to 5 PM.

  • Best for foundation settlement, sunken slabs and wet basements
  • Operating since 1982 under the Davis family, with Ram Jack Colorado acquired in 2012
  • Foundation repair and concrete lifting come first, and its basement, drainage and crawl space pages are generic, so ask for a specific waterproofing plan

Editorial Review

Our Take on Ram Jack of Colorado Inc

A long-established family firm with a strong Google record, but its identity is foundation repair and concrete lifting, so waterproofing buyers should ask exactly what system and warranty apply to water. We include it because Denver has few dedicated waterproofing companies and this one has the clearest local history and review base.

What We Like

  • Operating since 1982 under the Davis family, with Ram Jack Colorado acquired in 2012
  • 4.8 from 160 Google reviews, read October 21, 2026
  • Patented Ram Jack helical pier system alongside polyurethane foam concrete lifting
  • Free on-site evaluation and financing available
  • Limited lifetime warranty advertised for foundation repair

Things to Consider

  • Foundation repair and concrete lifting come first, and its basement, drainage and crawl space pages are generic, so ask for a specific waterproofing plan
  • Most Google reviews describe concrete lifting rather than basement water control, and one 2 star review reports a partly failed slab lift
  • The site is shared across three states with no Colorado licence number or named Denver team, and the office is in suburban Centennial

    Had Scott and Adam out to help correct garage grade with foamjacking and stem wall repair. The guys on the ground do Quality work and care about the outcome. It was also easy to make last minute changes when a small hiccup occurred. Would use Ramjack for all my foundation needs moving fwd

    They replaced the concrete for the front steps and porch going up to the front door of our house. They improved the layout of the steps eliminating one stop. The work was finished on time and looks great.

  • Steve & Patricia Conn5.0

    Would highly recommend talking to Ram Jack before starting ant work on your driveway. We had all of our questions answered, signed the contract and had the work initiated. Very happy with the structural elevation of our driveway and the waterproofing of the driveway seams.

Company Background

About Ram Jack of Colorado Inc

Ram Jack of Colorado Inc traces its story to 1982, when Tim Davis Sr. and his wife Joyce launched Straight Line Construction from a single truck in Pueblo, doing concrete repair for local homeowners. The family partnered with Ram Jack in 1993, Tim Davis Jr. and his wife Lauren took over ownership in 2009, and the company acquired Ram Jack Colorado in 2012 to work across the Denver metro area and the Front Range. Today the Colorado office sits at 14020 E Davies Ave in Centennial, a suburb south of Denver, and the company's own site lists Denver, Aurora, Lakewood, Littleton, Arvada, Englewood, Highlands Ranch, Parker, Castle Rock, Boulder and Longmont among the places it serves.

Be clear about what this firm is. Foundation repair with the patented Ram Jack helical pier system and polyurethane foam concrete lifting are the core business. The site also lists basement services, drainage services, crawl space services and vapor barriers for crawl spaces, but those pages are general and do not name specific waterproofing systems, so treat water control as a secondary offering. The company says it is bonded, licensed and fully insured, offers financing, and backs foundation work with a limited lifetime warranty. Every job starts with a free on-site evaluation.

Ram Jack of Colorado Inc has 4.8 from 160 Google reviews, read October 21, 2026. Reviewers name Kevin, a salesperson who explained options without pressure, and Adam, a foreman praised for precise work on three leveled slabs. One customer also credited the crew with sealing driveway seams. The fair criticism is a 2 star review from a homeowner whose basement slab lift only partly worked and who says the sales conversation did not prepare him for that outcome.

Ram Jack of Colorado Inc suits Denver homeowners whose water problem comes with settling, cracking or sunken concrete. It suits less well anyone who needs a dedicated interior drain and sump system or exterior membrane work and wants a specialist with a long list of named systems. Colorado has no statewide waterproofing licence, so check the company with Denver Community Planning and Development for contractor licence and permit rules, look up any plumbing work with the Colorado State Plumbing Board, confirm insurance, and read the BBB record. Before booking, ask who will actually do the waterproofing, what system they would install, what the warranty covers for water, and how a result is judged if the first attempt falls short.
