Stadium and arena construction and upgrades benefit from geotechnical construction techniques. Anchors and soil nails support excavations for stadium construction and upgrades. Micropiles and jacked piers provide support for increased loads from renovations. Vibro PiersTM, vibro replacement stone columns, and vibro compaction provide foundation support and subsurface densification for stadium facilities and playing fields. Injection systems control heave for stadium facilities, fields, and tracks. Compaction grouting mitigates sinkholes and increases the capacity of existing piles and drilled shafts. Hayward Baker has experience with the full range of geotechnical construction techniques to provide solutions for stadium construction and improvements.
