Specializing in Foundation Repairs Underpinning, Soils Modification and Compaction Grouting

Ultimo specializes in full service foundation soils stabilization and re-leveling of sunken structures, including homes, pools and tennis courts. Our methods for slope stabilization include limited access capabilities and are the fastest and most cost effective available today. Shown here is a typical failing slope and structure.

When Ultimo Construction is contacted in time, tests are made & determination of the condition of your slope allows us to use cost effective means of stabilizing and re-leveling your foundation system.

Compaction Grouting is a cost effective technique for the re-compaction and stabilization of sub-soils to greater depths than economically feasible with traditional methods. Depths of 25 to 75 feet are not uncommon. Often, soil problems can be traced to poorly compacted fill, loose soils, infiltration of water, and failure to over excavate and re-compact a building site properly.

Compaction Grouting has been found to reduce the possible damage of liquefaction of soils during seismic events. This technique uses a clear low slump grout that can be pumped slowly under high pressure into the soils with predictable results that will densify and re-compact the soils. When required, our high pressure pumps can sustain pressures that will fracture the soils and lift up the land and structures that lie upon it.

Foundation Underpinning offers a lasting solution to the foundation distress of buildings and structures. Underpinning Piers are very effective in emergency stabilization efforts needed to quickly secure a structure from sinking. The Mini Pile Underpinning Systems offer the fastest, thoroughly engineered, least intrusive and economical method of re-leveling a sinking structure. The amount of excavation required to permit accessibility is relatively small, therefore minimizing landscape repairs. Ultimo has used the combination of Atlas Systems and Compaction Grouting to successfully level and secure buildings.

Many factors may cause the settlement of a structure. Regardless of the cause, the structure has to be supported from bearing strata in order to avoid further settlement. The quality of any work depends of the quality of the product and the skills of the contractor. Atlas Piers are a field tested and proven product, typically used in foundation distress situations. They are constructed of the highest quality materials to ensure a long lasting permanent solution to foundation repair.

Helical Tieback Anchors and Piers simplify construction on slopes. The New Construction Pier is designed to carry the structural load and a Helical Anchor attached to the Pier Cap Assembly resists the lateral force. This application will work with continuous footings, individual concrete pier caps, or under column support. If you are making an addition to a structure or require additional foundation support for higher loads, the Atlas Helical Pier is the economical solution. The Atlas Helical Pier is ideal where there is limited access and where there is a fill material, organics or high water table located under the structure.

Retaining wall tieback applications are one of the first things that come to mind when you think about Helical Anchors. Atlas Helical Anchors are easy to install using portable equipment.

High pressure grouting is a method that is used to compact and stabilize compromised soils. This technique has been developed since the 1950's as a solution to control settlement. In recent years with the advancement of modern equipment, this technology has evolved to treat a variety of subsurface conditions for new and remedial construction. Great for foundation repairs.

Soils Modification services: High pressure grout is injected into subsurface soils to compact, stabilize and in some cases, lift. This method can also be used to inject chemicals into soils, in order to seal, glue, permeate or stabilize.

The specialized equipment utilized in Soils Modification is manufactured by The Ultimo Organization Inc. has been designed, tested and engineered to be operated in open as well as limited access areas such as home, back yards, garages, patios, basements, etc. With safety and production in mind, this line of equipment allows us to finish every project promptly and cost effectively. Soils modification is the term used for high pressure grouting.

The displacement of fill materials or native bearing soils beneath a sinking house concrete structures can be caused by seismic disturbance, water leaks, improperly drained surface runoff and vibration from machinery. The introduction of pressure grout through strategically located injection casings in order to compact the soil of a sinking house structure and fill voids is called sinking foundation. Ultimo Construction and Engineering can provide the expertise to sub-seal the voids that expose your structure to failure and sinking foundation. All the techniques mentioned above are used to prevent your house from sinking. We know the ins and outs of a sinking house.

Underground Pipe Abandonment:

1. Sinking House from disaster
2. Sinking Foundation from collapsing
3. Sinking House from caving in.

The process of underground pipe abandonment is a specialized field. Treatment of the underground where the pipe has been abandon is of high priority. Underground pipe abandonment has a long history which has caused concern to many engineering groups and the affects it has to the environment.
