+ Standard Penetration Test

The condition of subsurface soil determines the duration and costs associated with site preparation, type, and size of foundation to be used. Therefore, each project demands a genuine investigation involving borehole testing and collecting soil samples for laboratory testing. A Standard Penetration Test (SPT) is the most commonly used in-situ testing for evaluating in-situ soil properties.

With extensive geotechnical experience and advanced techniques DAS provides a fast and effective way to retrieve soil samples at an effective cost. Our equipment suite caters to any soil type and each of our drills are equipped with manual and automatic Standard Penetration Test (SPT) hammers allowing for consistent blow counts and effective geotechnical purpose.

If you cannot have a representative on site, we have you covered. Our team provide support with the sample collection and delivery, at the client’s designated location. Our experts ensure the soil samples are collected at set intervals and depths as specified by the engineering and construction requirements.

+ Staking & GIS Integration

DAS can provide in house start-to-finish staking as well as GIS integration with all of our on-site drilling and sampling onshore, shallow and transition water.

+ Equipment

We benefit from an expanded fleet of over 200 heavy and light duty pieces of rig equipment, including 30 buggy style rigs, 18 man-portable rigs, 10 tracked “mountain goat” rigs, multiple forestry mulchers for line clearance, and auxiliary equipment. Our narrow difficult access rigs are capable of accessing the most difficult sites and fit throughs. Utilizing survey vessels many of which are purpose-built and designed for efficient and integrated operations, we are able to acquire multi-disciplinary and complimentary data sets in a single mobilization.

Our diverse asset base provides unique capabilities and an ability to operate throughout the United States in any environment. From fields, mountains, backyards or forests, parking lots or residential structures to large commercial facilities DAS delivers total quality drilling performance on time and on budget. The variety of rig types allow us total control of drilling schedules and the ability to expedite your project.

+ Equipment Quality Guarantee

DAS fabricates and maintains its equipment to stringent industry specifications. With state-of-the-art cutting and welding stations, hydraulic hose machines, gas tank and powder box welding, drill stem extrusions and all the other peripheral parts the dedicated D.A.S. team is able to focus on delivering top quality results.
